Easycargo 40mm Heatsink Kit 40x40x11mm + 3M8810 Thermal Conductive Adhesive Tape, Cooler Aluminum Heat Sink for Cooling 3D Printer Stepper Motor TEC1-12706 Thermoelectric Peltier Module 40mmx40mmx11mm

The size is perfect for standard size stepper motors, the adhesive didn’t require any prep work and has held on upside down in temperature fluctuating chamber with no issues. I used an extra to mount to pancake stepper that is moving all the time. Still holding like a rock. My stepper motors seem to keep about 8 degrees colder during peak usage. Great gain for the price.

Worked great to cool down some 2.5" USB drives I had. Got out the dremel and cut holes in the plastic casings and popped on a heat sink to the top and bottom of the drive and dropped the temps a lot.

I put 8 of these on my DC DC battery charger in my camper van. Keeping the charger several degrees cooler than it was before. The adhesive bottoms work well. Seems like good value for the money. The small size also makes them versatile.

I used these on the power pack for my laptop. I noticed it gets extremely hot. I added 1 heatsink to each side and the temperature difference was remarkable. It was actually cool to the touch.

Does what it should do, works well.

Exactly as expected

A great addition to any electronic device such as audio to increase heat sink surface area and enhance passive cooling or incorporate into an active cooling system. Strong adhesive. Place carefully as you will only have one shot at mounting it! Quite difficult to remove and there’s also the risk of damage to your device should you try to.

Just the right size for SanDisk Extreme Pro: 2 on one side, and 2 on the other. Only working with them on one side for now though. Helps keep drive running cooler.
